The machine runs on 4 x AA batter-

ies,which slot into the side of the control

box. Access to the battery compartment

is via a sliding door with the correct way

to insert the batteries being shown on

the control box cover. On the opposite

side there is a connection for the head-

phones, which is sunken into the body

and is protected by a push fit rubber door

to stop dust, water, and debris from

entering the connection when the head-

phones are not being used.

Along with a very easy to understand

manual there is a comprehensive DVD.

This covers nine chapters including a

history of Minelab, VFLEX Technology

explained, the Control Panel and what

each button is used for, Pinpointing and

Discrimination set up, and a chapter on

detecting in the UK.

Field Trials

It would have been an easy option for

me to take the X-Terra 30 to some of my

more productive fields, but instead I

opted to try this new VFLEX technology

on some of the fields that I had been

avoiding due to the fact that they had

been used in the past by the farmer as a

dumpsite.

Two of the fields in particular were

heavily infested with rubbish, and it was

these fields on which I chose to carry out

part of the test.

The X-Terra 30 can be run in two dif-

ferent modes. One is an all-metal mode,

the other discrimination mode and selec-

tion is as simple as pressing the

touchpad on the console-marked pat-

terns to switch between the two. Both of

these modes are accompanied by a visual

display and an audio response.The target

ID display numbers on the X-Terra 30

range from -4 to 44, with a detected

object having one of the following 12

numbers: -4,4,8,12, 16,20,24, 28,32,36,

40 or 44. The number -4 indicates a fer-

rous object while the other 11 a

non-ferrous object.

As well as the ID numbers the X-

Terra has an added advantage of three

different tones - low, medium and high -

to indicate the target’s conductivity; a

low tone for ferrous and a medium to

high tone for non-ferrous.

For the first hour I ran the machine in

the All Metal mode and dug every signal

that read -4 to see if the machine was

giving an accurate reading. To my sur-

prise every reading was correct. I also

picked up two very nice buckles, a mus-

ket ball,a bag seal,and a pound coin - all

giving very positive audio and target ID

numbers.

The good finds all had a solid lock-on

meter reading, with a medium to high

tone.The bad targets were identified by a

low tone, an erratic meter reading, and a

display of -4. Having both an audio and

visual display that I could trust was really

saving me time and a lot of unnecessary

digging. Although the machine has a

fixed ground balance,I found that reduc-

ing the sensitivity stabilised the machine

so that I did not mask out the good sig-

nals.

The next few hours were spent run-

ning the machine in the discrimination

mode.This was a very big plus for me so

far as this machine was concerned.Being

able to accept or reject targets at the

press of a button made life very easy

indeed, and also saved a lot of unneces-

sary junk digging.

Another part of the farm that I had

been avoiding due to bullet shell cases

was a small wood situated at the bottom

of a steep field. This wood must have

seen some Home Guard action during

the Second World War as it is littered

with discarded .303 cases.

To overcome this problem it was just

a matter of finding one and then elimi-

nating similar targets using the

Accept/Reject button.

It was not long before I was finding

some nice coins,the best of these being a

cartwheel penny of George III and a Vic-

toria sixpence dated 1883. To my

amazement, in the same spot that I

found the sixpence was a shell case but I

had no indication that it was there until I

unearthed it while digging for the indi-

cated target.

To give some idea as to what the

audio sounds and the digital readings

might represent in the field I performed

the following air test using items that I

had found over the years.
